// This file represents the 64-bit PEB and associated data structures for 64-bit Windows
// This PEB is allegedly valid between XP thru [at least] Windows 8

//      https://github.com/giampaolo/psutil/commit/babd2b73538fcb6f3931f0ab6d9c100df6f37bcb     (RTL_USER_PROCESS_PARAMETERS)
//      https://redplait.blogspot.com/2011/09/w8-64bit-teb-peb.html                             (TEB)
//    2018-05-02:   -now can be compiled alongside windows.h (without changes) or by defining WANT_ALL_WINDOWS_H_DEFINITIONS so this file can be used standalone
//                  -this file may also be included alongside tebpeb32.h which can be found at http://bytepointer.com/resources/tebpeb32.h
//                  -64-bit types no longer clash with the 32-bit ones; e.g. UNICODE_STRING64, RTL_USER_PROCESS_PARAMETERS64, PEB64 (same result whether 32 or 64-bit compiler is used)
//                  -added more QWORD aliases (i.e. HANDLE64 and PTR64) so underlying types are clearer, however most PEB members remain generic QWORD placeholders for now
//                  -fixed missing semicolon bug in UNICODE_STRING64
//                  -added prliminary RTL_USER_PROCESS_PARAMETERS64 and TEB64 with offsets
//                  -included byte offsets for PEB64
